In the renewable energy field for semiconductors, energy alignment between the frontier orbitals of an organic chromophore and the band edges of a wide band gap metal oxide substrate is a key factor influencing charge transfer efficiencies and device properties. The poster will describe the synthesis and study of helical hexapeptides, synthesized from 2-amino isobutyric acid (Aib) residues, protected at the N-terminus with a carboxybenzyl group (Z) and at the C-terminus with either a carboxylic acid or an isophthalic acid (Ipa) anchor group, designed to establish a surface dipole layer on a TiO2 substrate, with the goal of influencing the energy levels of a co-adsorbed porphyrin. the peptides were bound on TiO2 nanoparticle films and single crystal TiO2(110)
